<P><STRONG>Functional Details</STRONG>
<P>
ImportSpreadsheet imports spreadsheet (i.e. tabular) ASCII data. Each column
in the file is imported as a separate component in the resulting output
field. The name of the component is taken from a name at the top of
the column in the file, if present. If no name is found, a default
name of "column#" is used instead.
<P>
If any column entry is NULL or consists of just white space this entry is
treated as invalid data in Data Explorer.
If it is a column of type
<UL COMPACT>
<LI>string
<BR>
A place holder of "&nbsp;" is placed at that entry,
<LI>float or int
<BR>
A -999 is placed at that entry.
</UL>
In addition, an "componentname missingvalues" component is created
which references those invalid entries. Also an "invalid positions"
component is created which is the union of all the
"componentname missingvalues" components. For more information on
invalid positions, see <A HREF="usrgu025.htm#HDRINVAL">"Invalid Positions and
Invalid Connections Components"</A> in <I>IBM Visualization Data Explorer
User&#39;s Guide</I>.

If you do not specify <TT><STRONG>delimiter</STRONG></TT>, white space
is assumed to delimit the columns.

</B></TD><TD><P>must be either "1-d" or "2-d". If you specify "1-d", then
positions of the output field will simply be the indices (row numbers)
from 0 to number-of-rows.  The field will have as many components as
there are imported columns, with each component named by the column name.
If you specify "2-d", then the output field will be a c&nbsp;x&nbsp;r grid,
where r is the number of imported rows, and c is the number of imported
columns. It will have
a single data component which contains all the values in the imported
rows and columns. If you specify "2-d", then the columns imported
can not mix string data with numerical data.
</TD></TR><TR VALIGN="TOP"><TD><P><B><TT><STRONG>categorize</STRONG></TT>
</B></TD><TD><P>specifies columns to be categorized, using the Categorize
module. If "allstring" is specified, all columns with a data type
of "string" are categorized. For additional information, see
<A HREF="refgu023.htm#HDRCATEGOR">Categorize</A>.
</TD></TR><TR VALIGN="TOP"><TD><P><B><TT><STRONG>headerlines</STRONG></TT>
</B></TD><TD><P>specifies the number of lines to skip before the start of the
data/column labels, for skipping comments at the top of the file.
Note that this would typically be necessary only when the data being
imported is all strings, or if you have comments at the top of the file
that could be misinterpreted as labels or data.
